| 摘要 |
The invention relates to a hollow body having a hollow cylindrical design at least in some regions, in particular to a camshaft (1), comprising an oil separation device that is integrated in a cavity of the hollow body, wherein a first pressure (p1) is present on an outlet side (5) of the oil separation device, and wherein a second pressure (P2) is present on an inlet side (4) of the oil separation device. According to the invention, the oil separation device is designed as a multiple thread worm body (2) which is connected to the hollow shaft section in a rotationally fixed manner. In addition, a shut-off element (6, 6') is provided, which on the inlet side (4) opens or closes the access to at least one worm channel (3b, 3c) of the multiple thread worm body (2) depending on the pressure difference (Deltap) between the second pressure (p2) and the first pressure (P1).
